不动点自由流的Packing熵
Packing entropy for fixed-point free flows
摘要:
设$(X,ϕ)$是一个无不动点的紧致流。通过考虑所有可能的时间重参数化,定义了$X$子集上的填充拓扑熵$h_{\mathrm{top}}^P(ϕ,K)$.对于不动点自由流,我们证明了如下结果:对于$X$的任意非空紧子集$K$,$$h_{\mathrm{top}}^P(ϕ,K)=\sup\{\overline{h}_μ(ϕ):μ(K)=1,μ\text{ is a Borel probability measure on} X\},$$其中$\overline{h}_μ(ϕ)$表示$X$上Borel概率测度$μ$的上局部熵.
英文摘要:
Let $(X,ϕ)$ be a compact flow without fixed points. We define the packing topological entropy $h_{\mathrm{top}}^P(ϕ,K)$ on subsets of $X$ through considering all the possible reparametrizations of time. For fixed-point free flows, we prove the following result: for any non-empty compact subset $K$ of $X$, $$h_{\mathrm{top}}^P(ϕ,K)=\sup\{\overline{h}_μ(ϕ):μ(K)=1,μ\text{ is a Borel probability measure on} X\},$$ where $\overline{h}_μ(ϕ)$ denotes the upper local entropy for a Borel probability measure $μ$ on $X$.
